As a part of the CSASN project, daily average discharge was estimated in three streams within the Toolik Inlet watershed. HOBO U20 data loggers were used for stage (water depth) data acquisition, and a rating curve relationship between stage and occasional dilution gauged discharge measurements was established to transform continuous stage measurements to continuous discharge measurements. The data included in this file is from I8 Outlet stream, 2010 season.

The Changing Seasonality of Artic Stream Systems (CSASN) was active from 2010 to 2012. The CSASN goal was to quantify the relative influences of throughflow, lateral inputs, and hyporheic regeneration on the seasonal fluxes C, N, and P in an arctic river network, and to determine how these influences might shift under seasonal conditions that are likely to be substantially different in the future. There were a number of TASCC and Plateau nutrient additions at each sampling location.
